ANK proteins constitute the largest family of poxviral proteins but their function and the significance of their abundance have remained an enigma. We propose that poxviruses use these unique ANK/F-box proteins to dictate target specificity to SCF1 ubiquitin ligases and thereby exploit the cell's ubiquitin-proteasome machinery.
